管店岩体岩石谱系单位划分及其就位机制探讨

GUANDIAN GRANITE BODY LITHODEMIC UNITE DIVISION AND EMPLACING MECHANISM DISCUSSION

本文从宏观（结构、构造、接触关系）微观（岩石化学、微量元素、稀土元素、副矿物）对比出发，按国际地层指南的将课成岩体“属于地层学和地层划分的范畴”的思路，将管店岩体划分成石马凹单元、南封单元、小寺王单元和祝刘单元四个单元,合并成管店超单元。并对岩浆受构造应力驱使由南向北挤侵就位证据进行了探讨。

This paper discussed texture.structure .contact; relationship, chemical compositions, microelements, REE and mineral assemblages, etc, of the Guandian granite body. Based on abrief of pedigree method, Guandian granite body can be divided into four lithodemic unites:Nanfeng unite,shima'ao unite, Xiaosiwang unite and Zhuliu unite. The paper also discussedthe evidence of the squeezing emplacement of the magma driven by tectonic stress.
